Hi Eugenio

Maybe its a timing problem... in case the ParentRefresh() function is called before win.creator is assigned

You can easily test that by placing an alert() between the two lines of script shown above, and waiting for a while before hitting Ok: if same error happens, that is the problem

If such was the case, you could use an interval to place a delay in the child script process.

HTH,
